In one embodiment, touch data and device data from multiple devices are received, and based on the received data, a cloud server can determine whether to combine the screen displays of different devices into a single virtual screen display and generate instructions accordingly for the devices to execute.

Abstract: A pen-input type information processor includes a pen holder for holding the pen, and a push type power switch provided on the pen holder. When the user takes out the pen after once pushing the pen downward, the power switch is turned on, starting power supply to the information processor. When the user puts the pen in the pen holder while pushing the pen downward, the power switch is turned off, and power supply to the information processor stops. In a preferred embodiment the pen can be replaced temporarily without turning on/off the power and switches are provided at each end of the pen holder to permit the holder to be used identically by either a left-handed or a right-handed user.
